Description

用于启动多波段传输的方法和设备 Method and apparatus for multi-band transmission start

技术领域 FIELD

[0001] 本发明涉及无线通信系统。 [0001] The present invention relates to a wireless communication system.

背景技术 Background technique

[0002] 超宽带(UWB)技术是在ECMA 368/369规范下被标准化的。 [0002] Ultra wideband (UWB) technology is standardized under the ECMA 368/369 specification. 更特别地,ECMA368/369标准规范了支持数据率达到480兆每秒(Mbps)的WTRU的分布式媒介接入控制(MAC)层和物理(PHY)层。 More particularly, ECMA368 / 369 standards supported data rate of 480 megabits per second distributed media (Mbps) of the WTRU access control (MAC) layer and a physical (PHY) layer. PHY层被设计成运行在3. I到10. 6千兆赫(GHz)频谱并已经被接受作为诸如下一代蓝牙®、无线通用串行总线(WUSB)和无线火线(IEEE 1394)等技术的常用平台。 The PHY layer is designed to run 3. I to 10.6 gigahertz (GHz) frequency spectrum and has been accepted as a common Bluetooth ®, Wireless Universal Serial Bus (the WUSB) and Wireless Firewire (IEEE 1394) as the next-generation technologies such as platform.

[0003] ECMA 368PHY层使用多波段正交频分复用(MB 0FDM)以传输信息。 [0003] ECMA 368PHY layer is formed using a multi-band orthogonal frequency division multiplexing (MB 0FDM) to transmit information. ECMA 368PHY层规范运行频谱被划分成5个无线电波段群组,其中每个无线电波段,或等价载波空间为528MHz。 ECMA 368PHY layer specification operation frequency spectrum is divided into 5 radio band groups, wherein each radio band, or equivalent carrier space 528MHz. 前四个无线电波段群组具有三个528MHz的无线电波段,而第五个波段群组包括两个528MHz的无线电波段。 The first four radio band groups have three radio bands of 528MHz, while the fifth band group includes two radio bands of 528MHz. 运行在第一无线电波段群组的能力是强制的。 The ability to run in the first radio band group is mandatory. 然而,运行在其他无线电波段群组中是可选的。 However, running the other radio band group is optional.

[0004] ECMA 368MAC层具有完全分布式的架构并向上层协议或适应层提供MAC服务。 [0004] ECMA 368MAC layer architecture is fully distributed to the upper layer protocol or adaptation layer provides MAC services. 没有中心协调设备并且每一设备支持所有的MAC功能。 There is no central coordinating device and each device supports all MAC functions. 在无线电范围内的设备使用周期性信标帧相互协调。 Devices within radio range using the periodic coordination channel beacon frame. 这些信标帧提供网络定时、调度和能力信息,也提供其他信息和功能。 These beacon frames provide network timing, scheduling and capability information, provides additional information and functionality.

[0005] 信标帧提供信息的一种方式是经由包括在信标帧或命令帧中的信息元素(IE)。 One way [0005] The beacon frames provide information is via an information element in the beacon frame or in a command frame (IE). 这一IE可以包括信标周期(BP)转换IE和/或分布式保留协议(DRP) IE。 This IE may include a beacon period (BP) Conversion IE and / or a distributed reservation protocol (DRP) IE. 更特别地BP转换IE可以包括元素ID字段、长度字段、BP移动倒计时字段、信标时隙偏移字段和BP开始(BPST)偏移字段。 More particularly BP transition IE may include an element ID field, a length field, a BP move countdown field, a beacon slot offset field, and a BP start (BPST of) Offset field.

[0006] 另外,来自ECMA 368的MAC超帧结构包括信标周期(BP)和媒介接入时隙(MAS)。 [0006] Further, from the ECMA MAC superframe structure 368 includes a beacon period (BP) and medium access slots (MAS).

[0007] ECMA 368/369标准当前支持的机制和速率的一个问题是,支持一些应用是不足够的,例如高清晰度数字电视(HDTV),其根据HDTV的格式需要IGbps或更高的数据率。 One problem [0007] ECMA 368/369 standard currently supports the mechanism and rate that is insufficient to support certain applications, such as high-definition digital television (HDTV), which according to the data rate of the HDTV format requires more or IGbps . 因此,提供一种启动(enable)多波段传输的方法和设备,以便能够在下一代(NG)UWB中实现高数据率,将是很有益的。 Accordingly, a promoter (enable) Method and apparatus for multi-band transmission, to be able to achieve high data rates in next generation (NG) UWB will prove to be very useful.

具体实施方式 Detailed ways

[0014] 下文引用的术语“无线发射/接收单元(WTRU) ”包括但不局限于用户设备(UE)、移动站、固定或移动用户单元、寻呼机、蜂窝电话、个人数字助理(PDA)、计算机或能在无线环境中工作的其它任何类型的用户设备。 [0014] When referred to hereafter, the term "wireless transmit / receive unit (the WTRU)" includes but is not limited to a user equipment (the UE), mobile station, fixed or mobile subscriber unit, a pager, a cellular telephone, a personal digital assistant (PDA), a computer or capable of operating in a wireless environment any other type of user equipment. 下文引用的术语“基站”包括但不局限于节点-B、站点控制器、接入点(AP)或是能在无线环境中工作的其它任何类型的接口设备。 The term "base station" includes but is not referred to hereafter limited to a Node -B, any other type of interfacing device a site controller, an access point (AP) or capable of operating in a wireless environment.

[0015] 图I显示了包括多个WTRU 110的分布式无线通信系统100的实例。 [0015] Figure I shows an example of a wireless communication system comprises a distributed plurality WTRU 110 100. 如图I所示,WTRU 110都相互通信。 As shown in FIG. I, WTRU 110 can communicate with each other. 但是,尽管显示了相互通信的三个WTRU110,应当注意的是任何数目的WTRU 110可以被包括在分布式无线通信系统100中并且每个WTRU 110可以与每个其它WTRU 110通信或不与每个其它WTRU 110通信。 However, although three WTRU110 display communicate with each other, it should be noted that any number of WTRU 110 may be included in the distributed wireless communication system 100 and every WTRU 110 may communicate each other WTRU 110 with or without each other communications 110 WTRU.

[0016] 图2是WTRU 110的功能性框图。 [0016] FIG. 2 is a functional block diagram of the WTRU 110. 除了在典型WTRU可以找到的模块,WTRU 110包括处理器115、接收机116、发射机117和天线118。 In addition to the module can be found in a typical WTRU, WTRU 110 includes a processor 115, a receiver 116, a transmitter 117, and antenna 118. 处理器115被配置成如下面详细描述的实例的方式启动多波段传输。 Examples of processor 115 is configured as a manner described in detail below starting multiband transmission. 接收机116和发射机117与处理器115通信。 Transmitter 117 and receiver 116 communicate with processor 115. 天线116与接收机116和发射机117两者通信以方便无线数据的发射和接收。 The antenna 116 117 communicate with both the receiver and the transmitter 116 to facilitate the transmission and reception of wireless data. 尽管如图2中显示的WTRU110中描述的只有一个发射机、接收机和天线,但WTRU 110可以包括多个发射机、接收机和天线。 Although shown in FIG WTRU110 2 described only one transmitter, receiver and antenna, but the WTRU 110 may include a plurality of transmitters, receivers and antennas.

[0017] 图3是启动多波段传输的方法300的流程图。 [0017] FIG. 3 is a flowchart of a method 300 of multi-band transmission start. 方法300的实施为实施NG UffB技术的WTRU提供更高的数据速率。 The method of embodiment 300 of the WTRU embodiment NG UffB technology provide higher data rates. 另外,通过利用多于一个无线电波段可以扩展带宽,现在的带宽是528MHz。 Further, the bandwidth can be extended by using more than one radio band, the bandwidth is now 528MHz.

[0018] 在步骤310,WTRU 110在多于一个无线电波段上传输信标。 [0018] In step 310, WTRU 110 transmit a beacon on more than one radio band. 所述信标包括在多于一个无线电波段上与WTRU 110传输协调相关的信息。 The beacon includes coordination information associated with the transmission WTRU 110 on more than one radio band. 传输可以发生在相邻无线电波段或不相邻无线电波段,并且无线电波段可以包括单无线电波或双无线电波的选择。 Transmission may occur in the adjacent radio bands or non-adjacent radio bands, and the radio bands may include selecting a single radio or dual-radio waves waves.

[0019] WTRU 110使通过所有无线电波段的信标协调或同步(步骤320)。 [0019] WTRU 110 that the letter marked by coordination or synchronization of all radio bands (step 320). 这一同步可以包括对各个波段上的不同信标对齐信标周期(BP)开始时间。 This synchronization may include different beacon period start time on the beacon channel aligned on each band (BP). 可替换地,WTRU 110可以知道在不同波段中的BP开始时间之中的相关偏移量。 Alternatively, WTRU 110 may know the BP start time among different bands associated offset. 因为BP扩展到比信标传输持续时间长,BP的部分时间重叠会发生。 Because the ratio of BP to beacon transmission extend long duration, BP partial time overlap occurs. 另外,可以达到非重叠信标传输。 Further, it is possible to achieve non-overlapping beacon transmission.

[0020] 如果WTRU 110包括单无线电发射机,WTRU 110在多于一个无线电波段上传输以增加数据率。 [0020] If the WTRU 110 includes a single radio transmitter, the WTRU 110 on more than one radio band to increase the data transmission rate. 例如,WTRU 110将在相邻无线电波段上传输。 For example, WTRU 110 will transmit on adjacent radio bands. 在这种情况下,WTRU 110通过在扩展带宽传输(EBT)中的所有无线电波段中对齐信标周期开始时间来使信标同步(步骤320)。 In this case, WTRU 110 to make the beacon synchronization (step 320) by all radio bands in the extended bandwidth transmission (the EBT) aligned in a beacon period start time.

[0021] 在另一假定,WTRU 110可以在第一无线电波段上传输,然后转换,或“跳”到第二无线电波段,其中WTRU 110在第二无线电波段监控BP中的信标并传输。 [0021] In another assumed, WTRU 110 may transmit on a first radio band, then switch, or "jump" to a second radio band, wherein the WTRU 110 to monitor the beacon in the BP and transmits on the second radio band. 这一假定的实例可以包括WTRU 110利用在多波段上的资源的情况,例如在第一无线电波段上的媒介接入时隙(MAS)的一半和在另一个上的一半,所述WTRU 110包括单一无线电波。 This assumption may include examples where WTRU 110 use resources on multiple bands, such as half and half on the first radio band medium access slot (MAS) on the other, the WTRU 110 comprises single radio waves. 在这种情况下,在不同波段上的BP不可以被对齐,但是可以具有已知的偏移。 In this case, BP on different bands may not be aligned, but may have a known offset. 在这一假定中的WTRU110在时间上的不同点的两个信标。 WTRU110 in different points on the assumption of the two beacon period. 这一假定也可以方便使用一个信标,如主信标,在多个波段上经由DRP保留资源。 This assumption may be convenient to use a beacon, such as the primary beacon, reserving resources via DRP on multiple bands.

[0022] 可替换地,WTRU 110可以仅具有在非信标周期(即非BP)被利用的EBT。 [0022] Alternatively, WTRU 110 may have EBT only non-beacon period (i.e., non-BP) was utilized. 例如,WTRU 110可以利用单无线电发射机,该单无线电发射机以在BP期间发生的单无线电波传输在两个相邻波段上同时传输。 For example, WTRU 110 may utilize a single radio transmitter, the radio transmitter in a single single radio wave transmission BP occurring during simultaneous transmission on two adjacent bands. 这将启动信标传输的适当的接收。 It receives the appropriate starting beacon transmission.

[0023] 在另一假定,WTRU 110可以包括多于一个无线电发射机。 [0023] In another assumed, WTRU 110 may include more than one radio transmitter. 图4是启动多波段传输的替换方法400。 FIG 4 is a multi-band alternative starting transmission 400. 如在方法400中所描述的,WTRU 110包括多个无线电发射机。 As described in the method 400, WTRU 110 includes a plurality of radio transmitters.

[0024] 在步骤410,WTRU 110的分离的无线电波,或无线电发射机在分离的无线电波段上独立传输。 [0024] In step 410, the WTRU 110 separate radio waves, or radio transmitter on a separate independent transmission radio band. 例如,第一无线电波可以在一个无线电波段上传输,而第二无线电波可以在第二无线电波段上传输。 For example, the first radio wave may be transmitted on one radio band while a second radio wave can be transmitted on a second radio band. 在这种情况下,对于BP同步或对齐来说是没有必要的,因为两个信标在分离的无线电波段上传输并且互相不冲突。 In this case, for BP synchronization or alignment it is not necessary, since the two beacons transmitted on separate radio bands and do not conflict with each other.

[0025] WTRU 110监控传输媒介(步骤420),以监控信标帧的存在(步骤430)。 [0025] WTRU 110 monitoring the transmission medium (step 420), is present (step 430) to monitor a beacon frame. 如果没有信标帧存在(步骤430),则WTRU 110创建BP (步骤440)。 If no beacon frames exist (step 430), then the WTRU 110 creates on BP (step 440). 更特别地,在EBT的所有波段中的BP开始时间对齐被利用以便在所有波段对于WTRU 110的EBT的保留被对齐。 More particularly, BP start time in all bands are aligned EBT is utilized so as to be aligned for the retention of the EBT WTRU 110 in all bands. 这将达到的一个假定是重新使用BP转换IE以使BP在所有无线电波段上同步BP。 This is assumed to be achieved a transition IE reused so BP BP BP synchronized on all radio bands.

[0026] WTRU 110在所有波段上协调信标同步(步骤450)。 [0026] WTRU 110 coordinating beacon synchronization (step 450) in all the bands. 在一个实例中,为EBT配备的WTRU 110根据其自身BP在给定无线电波段上传输信标帧(步骤460)。 In one example, as the EBT WTRU 110 in accordance with its own BP in a given band on the radio transmission of the beacon frame (step 460). 接收这一信标帧的其他WTRU 110用BP转换IE对齐各自的BP。 Receives this beacon frame by another WTRU 110 BP BP respective aligned IE converter. 例如,在转换到新的BP之前,WTRU 110可以在其先前BP上传输信标,在该先前BP上BP转换IE被添加以指示到新BP的移动。 For example, before switching to the new BP, WTRU 110 may transmit its previous beacon on BP, it is added to indicate the move to the new BP in the previous BP BP conversion IE. 配备WTRU 110的EBT可以在所有无线电波段上同步传输,或从无线电波段到无线电波段的相继(sequentially)传输。 WTRU EBT 110 may be equipped with synchronous transmission on all radio bands, or successively (sequentially) transmitted from the radio band to radio band. 由此,结果是在所有波段中的BP都与EBT WTRUl 10的BP对齐。 Thus, a BP result in all of the bands are aligned with the BP EBT WTRUl 10. 这需要多个超帧以在这种状况下执行。 This requires multiple super-frames to perform in this situation.

[0027] 可替换地,WTRU 110可以引入新的EBT BP转换IE到在系统中的其他WTRU,以指示它们来将其BP同步到在EBT BP转换IE指定的时间上的指定的值。 [0027] Alternatively, WTRU 110 may introduce a new IE to convert the EBT BP other WTRU in the system, to indicate that they synchronize to its BP in the EBT BP converted to the value specified on the IE specified time. 由此,新的EBT转换IE在字段上包括新的信标周期定时和改变BP的时间。 Accordingly, the new EBT conversion IE includes a new beacon period timing and a time to change the BP in the field. 因此,WTRU 110可以在被传输的信标上提供EBT能力,如缺省信道和缺省扩展信道。 Thus, WTRU 110 may provide EBT capabilities is transmitted on the beacon, such as the default channel and a default expanded channel.
